SpaceX Shows Stainless Steel Starship Parts And Hopper Will Have a Mirror Finish

The SpaceX Starship is being made from stainless steel. The skin will get too hot for paint. The stainless steel will have a mirror finish for maximum reflectivity.

It will require much less shielding.

The usable strength to weight ratio of full hard stainless steel at cryogenic temperatures is slightly better than carbon fiber and at high-temperature stainless steel is vastly better.

The hopper Starship will have three raptor engines.
